Line Chart unusable #215

Closed trenkert closed 2 years ago

trenkert commented 2 years ago
Timeseries version

0.4.1

Orange version

3.32.0

Expected behavior

In earlier versions of Orange3 and of the timeseries widget, Line Chart was completely usable.

Actual behavior

Now, when I pull the Line Chart widget into the canvas, it simply gives an error and remains unusable. image

Steps to reproduce the behavior

Pull in the widget and wait for a couple of seconds.

Instability is caused by connection between Orange and highcharts through QWebKit. We are aware of the problem and complete reimplementation of the widget is already underway.

The problem is an old one, and the current version shouldn't have made it any worse than it was.

@PrimozGodec, @markotoplak, is there any simple and ordinary-user-friendly way to downgrade an add-on, so Paul can check whether this would indeed help?
